The measurement uncertainty refers to the random uncertainty in the measurement process. It is complete when the measured data and uncertainty is provided at the same time. This paper described the digestion of samples in activated sludge by microwave,and zinc concentration in the digested samples was measured by FAAS. The measurement uncertainty is evaluated based on the guide of uncertainty evaluation and denotation for measurements. The sources of uncertainty in the measurement were analyzed. Every uncertainty component was evaluated and quantified. The combined standard uncertainty and the expanded uncertainty were expressed. The result of the measurement of Zinc in sludge sample was expressed as (465±11) mg/kg, k=2.
